Product Details

TZP80-2405/S AC-DC Product Description

The TDK-Lambda TZP80-2405/S is an 80W dual-output AC/DC power supply engineered for the demanding power integrity requirements of industrial data networks and smart factory automation architectures. Delivering stable +24V and +5V outputs simultaneously, this unit anchors the power layer of distributed control systems where uninterrupted energy supply is the foundation of every data transaction — from field-level sensor polling to SCADA dashboard refresh cycles.

In modern industrial connectivity deployments, power quality is inseparable from data quality. Voltage ripple, transient spikes, and brownout conditions at the power rail translate directly into communication errors, CRC failures, and dropped packets across Modbus RTU, PROFIBUS DP, EtherNet/IP, and PROFINET segments. The TZP80-2405/S addresses this with tight output regulation, low ripple noise, and wide input voltage tolerance (85–264V AC), making it a reliable backbone component for mixed-protocol factory networks where multiple fieldbus standards coexist on the same production floor.

A smart factory data chain begins at the physical layer — and the TZP80-2405/S powers that layer with precision. Consider a typical EtherNet/IP topology: field sensors and actuators connect to a Siemens ET 200SP remote I/O station, which feeds real-time process values upstream to a Siemens S7-1500 PLC over PROFINET. The PLC's 24V DC logic rail, powered by the TZP80-2405/S, maintains deterministic scan cycles even under transient load conditions caused by simultaneous I/O updates across dozens of distributed nodes.

At the network layer, an industrial managed Ethernet switch — such as a Hirschmann RS20 or Phoenix Contact FL SWITCH — aggregates data from multiple PLC subnets and forwards it to the plant SCADA server. The switch's 24V power input, supplied by the TZP80-2405/S, ensures zero-downtime port availability critical for time-sensitive PROFINET IRT frames. Alongside the switch, a Moxa MGate MB3480 Modbus-to-EtherNet/IP gateway bridges legacy Modbus RTU devices — older variable frequency drives, flow meters, and pressure transmitters — into the EtherNet/IP backbone, with its logic circuits drawing from the same stable 5V rail.

HMI visualization is handled by a Weintek cMT Series HMI panel mounted at the operator station. The panel's 24V supply, sourced from the TZP80-2405/S, sustains continuous touchscreen responsiveness and real-time tag polling from the SCADA historian. Alarm events triggered by out-of-range analog inputs from Endress+Hauser Cerabar pressure transmitters are timestamped at the field level and propagated through the data chain to the SCADA alarm management module without latency introduced by power instability.

For remote diagnostics, an edge gateway module — such as an HMS Anybus X-gateway or Advantech WISE-710 — aggregates OPC-UA data from the PLC and forwards it over 4G/LTE or fiber to the cloud-based MES platform. This gateway's dual-voltage requirement (24V for communication logic, 5V for embedded processing) is precisely matched by the TZP80-2405/S dual-output architecture, eliminating the need for a secondary DC/DC converter and reducing panel footprint. The result is a leaner, more reliable edge node that sustains continuous data uplink even during grid voltage fluctuations common in heavy industrial environments.

Variable frequency drives — including ABB ACS580 and Danfoss FC302 series — rely on stable 24V control power for their fieldbus communication cards (PROFIBUS DP or EtherNet/IP option boards). When these drives are integrated into a coordinated motion control loop managed by the S7-1500 PLC, any power rail instability causes communication timeouts that interrupt torque ramp sequences and trigger safety shutdowns. The TZP80-2405/S eliminates this failure mode by providing a regulated, low-ripple 24V supply that keeps drive communication cards online through load transients.

Data visualization dashboards on the SCADA server — running platforms such as Ignition by Inductive Automation or Wonderware System Platform — aggregate tag data from all connected nodes. The server's UPS-backed 24V auxiliary rail, reinforced by the TZP80-2405/S, ensures that historian write cycles and alarm acknowledgment workflows are never interrupted by momentary power events, preserving data integrity across the full production shift.

Protocol fragmentation is one of the most persistent challenges in brownfield factory upgrades. When a plant runs Modbus RTU on legacy drives, PROFIBUS DP on older I/O modules, and EtherNet/IP on newer PLC racks simultaneously, the power infrastructure must support gateway devices that translate between all three. The TZP80-2405/S dual-output design powers both the communication processor (5V) and the fieldbus interface circuitry (24V) within a single gateway enclosure, reducing BOM complexity and improving mean time between failures.

Data island elimination requires reliable power at every node in the network. Remote I/O stations installed at machine-level — far from the main control panel — are particularly vulnerable to voltage drop and noise. The TZP80-2405/S wide input range and high efficiency (up to 87%) minimize heat generation in compact enclosures, allowing deployment in distributed junction boxes without forced cooling, which is essential for maintaining network uptime in harsh production environments.

Remote monitoring and transparent production depend on continuous data flow from field devices to the SCADA layer. Any power interruption at a remote I/O station or gateway node creates a data gap that corrupts trend charts, invalidates OEE calculations, and delays alarm response. The TZP80-2405/S built-in overvoltage, overcurrent, and short-circuit protection ensures that fault conditions at one node do not cascade into adjacent network segments, preserving system-wide data continuity.

System expansion in growing smart factory deployments requires power supplies that can be added incrementally without redesigning the power distribution architecture. The TZP80-2405/S DIN rail form factor and standard terminal block connections allow new nodes — additional remote I/O stations, new gateway modules, or supplementary HMI panels — to be integrated into existing panel layouts without structural modifications, supporting phased automation rollouts aligned with production capacity growth.

Q1: Does the TZP80-2405/S support powering PROFINET IRT communication nodes without introducing timing jitter?A: Yes. The TZP80-2405/S tight output regulation (±1% typical) and low ripple noise ensure that PROFINET IRT-capable devices — including Siemens ET 200SP I/O modules and PROFINET-enabled drives — receive a stable 24V supply that does not introduce timing anomalies into the isochronous real-time communication cycle. This is critical for motion control applications where cycle times are below 1ms.

Q2: Can this unit power both a Modbus-to-EtherNet/IP gateway and its associated managed switch port simultaneously?A: The dual-output architecture (+24V / +5V) allows the TZP80-2405/S to power a gateway module's communication processor (5V rail) and its Ethernet interface circuitry (24V rail) from a single unit. For managed switch power, a dedicated 24V output channel can supply the switch independently, provided total load remains within the 80W envelope. Always verify combined load against the derating curve at your ambient operating temperature.

Q3: What remote diagnostic capabilities does the TZP80-2405/S support for predictive maintenance integration?A: While the TZP80-2405/S is a passive power supply without onboard communication interfaces, it is designed to power active diagnostic nodes — including edge gateways with OPC-UA output, remote I/O modules with diagnostic telegram support, and SCADA-connected alarm servers. Its stable output ensures that diagnostic data streams from connected devices remain uninterrupted, supporting continuous predictive maintenance data collection without power-induced gaps.

Q4: What does the 12-month warranty cover, and what is the pre-shipment testing process?A: Every TZP80-2405/S unit undergoes full-load burn-in testing and output voltage verification before shipment. The 12-month warranty covers manufacturing defects, output regulation failures, and component-level faults under normal operating conditions as defined in the TDK-Lambda TZP series datasheet.
